of a tubula handle employed in this device.

tubular handle 34 is provided and is of such size that it may embrace at one end the ra- In the construction oi" the machine as shown, a Jframe is built up of longitudinal dial portions of the eye-stems 29, 30. Slots 35, 36, of unequal length, are `formed longibars 10, 11 connected near their ends by cross-bars 12, 13. Angle plates 14, 15 are tudinally oi' one end portion of the handle 34 diametrically opposite each other.

fixed to and extend longitudinally of the in- In practical operation the machine is ner faces of the bars 10, 11. The 'angle plates 14, 15 have their horizontal vflanges explaced on the bottom of an excavation, the stem 26 of the desired length and the auger tending inward toward each other and ierced by a plurality of apertures 16, 17. IIachine heads 1S, 19 are mounted trans- 27 are mounted thereon. The eye-stems are turned upward and a handle 34 is applied thereto in such manner that the slots 35, 36

versely of the frame and are connected at their ends by plates 20, 21 rigidly secured receive the end portions of the spring 33 and pawl 32. If it is desired to rotate the auger thereto. Pins 22 are formed on and extend upward from end portions of the machine 27 in the direction of the arrow a in Fig. 2 the handle is mounted as shown and in such pohead 18 and pins 23 are formed on and extend downwardly from the end portions of the machine head 19. The pins 23 normally engage in one or the other of the holes 16, 17 in the angle plates 14, 15 and prevent longitudinal movement of the machine head portions of the spring 33 and pawl 32 to rise i'reely within it, while the shorter slot 35 will not permit the adjacent end portion of the and plates 20, 21 longitudinally o'l' the frame. spring 33 to rise materially, thus holding the I`he machine heads and plates 20, 21. may be adjacent end portion ci the pawl 32 norinverted and turned end for end m order mally in contact with the gear 28. Then the that the pins 22 on the head 1S may engage one or the other of the holes 16, 17 in the angle plates, thus reversing the direction oi operation of the machine as hereinafter deupper end portion of the handle 34 is moved manually in the direction of the arrow b, thus causing the pawl 32 to engage and rotate the gear 28 in the desired direction. Such rotasition the slot 36 permits the adjacent end tion of the stem 26 and bers to move longitudinally through engagement of the screw 25 in engagement with the box 18. Such laterally into the earth. When it is desired to unscrew the auger, the handle 34 is removed and reversed relative to the eye-stems so that the slot 35 receives the opposite end portions of the spring 33 and pawl 32. Thus the action of the pawl 32 is reversed and o posite movement of the handle 34 effects a reverse movement of the feed-bar, stem and auger. When it is desired to bore into the earth in the opposite direction, the stem 26 and auger 27 are detached from the feed-bar, the feed-bar, machine heads 18, 19 and plates 20, 21 are lifted out and turned over end for end and replaced, thus disengaging the head 19 from the angle plates and engaging the head 18 with said plates. Then the stem 26 and auger 27 are attached to the feed-bar and extend through the cross-bar 13. Before the machine is inverted the handle 34 is removed and after the operation of inversion, the eye-stems are turned around the feed-bar s'o that they are directed upwardly and can again receive attachment of the handle. After the machine is inverted as described, the feed-bar and connected parts may be operated by oscillation of the handle 34 as hereinbefore described.

e claim as our invention- 1. An earth boring machine, comprising a frame, angle plates on said frame, connected machine heads in said frame and engaging said angle plates, a feed bar mounted in said machine heads, screw connections between said feed bar and one of said machine heads, means for connecting an auger to said feed bar and means for rotating said feed bar.

2. An earth boring machine, comprising a gear revolves the feed-bar 24,

auger 27 and causes said memoperation advances the auger frame, angle plates on said frame, machine heads invertibly mounted on said angle plates, connections between one of said machine heads and the angle plates, a screw box in one of the machine heads, a smooth box in the other machine head, a feed bar mounted in said boxes, an auger attached to said feed bar, and means fororotating said feed bar.

3. In an earth boring machine, angle plates formed with holes, a machine head and pins on said head engaging in said holes.

In an earth boring machine, angle plates formed with holes, machine heads, plates connecting said machine heads, and pins on said machine heads adapted to engage in said holes.

5. In an earth boring machine, machine heads arranged parallel with each other, one of said heads formed with a screw box, the other of said heads formed with a smooth box, plates connecting said heads, means for anchoring said heads, a feed bar mounted in the boxes of said heads, a gear on said feed bar, eye-plates on said feed bar adjacent said gear, a reyersible pawl on said eye-plates engaging said gear and a handle removably and replaceably mounted on said eye-plates.

6. In an earth boring machine, a feed bar, a gear thereon, eye-plates loosely mounted on said feed-bar, a pawl on said eye-plates adapted to engage said gear, a spring mounted on said platesv and adapted to engage said pawl, and a handle mounted on said eyeplates, said handle formed with opposite slots of unequal length adapted tov limit oscillation of the pawl and determine the action of said pawl on the gear.
